I don't know what exactly happens, but TyphoonLabs Shader Designer doesn't work on systems with NV cards form some time. I'm not sure, but probably for couple of years. If you really need it try to install some older drivers (with GL 2.1 support only), or try to debug it. It breaks while trying to apply fragment processor:

And I thought it was just me who couldn't get any version to work on my nVidia card or the iMacs' ATi Mobility (which run UT3 pretty well actually) chipsets.

one typical issue with _old_ application is a buffer overflow when they get the OGL extension string. many applications allocate a char[MAX] on the stack and copy the string into it; MAX is often a hardcoded value, which ends up being too small a few years later when many new extensions have been added.

on AMD platform, you could try to rename the application to x29.exe; we already have a workaround for that apps in place which will limit the size of the string.
